blitz, swordtech, and other battle animations

how about changing the health skill? Banon's skill set?

Everything is possible. This is probably what you are looking for:

Code:

Health animation?

C1/BB62:    20F7BB      JSR $BBF7        (from C1/B76F, X = 1A)
C1/BB65:    900E        BCC $BB75
C1/BB67:    2035BC      JSR $BC35
C1/BB6A:    A26C0F      LDX #$0F6C
C1/BB6D:    20F5B7      JSR $B7F5
C1/BB70:    A927        LDA #$27
C1/BB72:    20E1BB      JSR $BBE1
C1/BB75:    60          RTS

I don't think you can edit those graphics with FF3usME or the MDE editor unless I'm mistaken. As for this assembly routine, I don't know exactly what it does (aside of probably loading health's graphics) but it jumps (JSR) to multiple places and studying it would require some time. I should be in bed since a long time lol...Sorry if I can't help more for now...Someone might come up with a better answer...
